501 / 508 Hard Drive Upgrade

[intribe]

Is it possible to upgrade the hard drive in a 501 / 508?

If so, how, and is the receiver smart enough to record for a longer duration once the upgrade is completed?

It is possible but difficult to do. It is not as simple as the dishplayer (7100/7200) or the Tivo's.
